Evaluation of neutrino masses from $m_{ββ}$ values
Abstract
Description
A neutrino mass matrix is considered under conditions of a CP invariance and a small reactor mixing $θ_{13}$ angle. Absolute mass values for three neutrinos are evaluated for normal and inverted hierarchy spectra on the ground of data for oscillation mixing neutrino parameters and an effective neutrino mass $m_{ββ}$ related to a probability of neutrinoless two beta decay.
